Remember that stage directions are written into the script of a play, they indicate the actors and everyone reading it, about: the location of a scene, a sound (and where it's comming from), how does a person, place or thing looks, and the psychological or emotional stage of a character. 
So the correct answers are: 
- Character's action and behaviours: here we can see that Nora pays the Porter, shuts the door, takes off her hat, etc. 
- Character's gestures: we can see the directions indicate that Nora laughs to herself.
